General Information About Diagrams and Schematics
General Information About Diagrams and Schematics The chassis wiring used in these vehicles conforms to the electrical circuit identification standard ES-1359 and in addition to surface marked ID circuit numbers, generally utilizes the colors that are indicated in Table 1. MONOTROL®, engine harnesses, wiring to sensors, and other applications vary with respect to wire colors. Diagrams and schematics in this manual can be viewed and printed in color. If not printed or viewed in color, refer to the electrical circuit
identification located on schematic circuits. When viewing a color version of the diagrams and schematics, the white chassis wires are seen as yellow. Other wires are shown in colors similar to actual colors, i.e. tan shows as yellow. Use circuit identification for true wire color. Refer to Diagnostic Troubleshooting Manual 9000SRM1112 Section 9030, Group 03 - General Maintenance and Diagnostic Data, for further information.
